Bolt Lift Kit

[bbradford71]

I recently purchased a bolt lift kit and tried to install it last night. once I put the lift kit into my bolt there are no threads left showing and I can not get the screw that screws into the back end of the bolt to screw in. What am I doing wrong, any help is appreciated.


Thanks

Uncock the firing pin and install the screw. Recock and you are ready to go.

This is going to sound very stupid, how do you uncock the firing pin, I am new to working on my own guns.

Thanks

Whats does the kit do?

[bbradford71]

From my understanding it allows for the bolt to cycle more smoothly and with less effort

In order to get more threads, you have to make sure the cocking pin is forward. With the cocking pin forward you can turn the bolt screw in just a bit (not too much). After you do this you have to push the cocking pin back into the cocked position.....to do this I place the back of the bolt screw on a flat wooden wall surface and push the cocking pin back with a piece of wood. After that screw the bolt screw in all the way.

Lighten your wallet, not much more than that unless you do other things too

+1 smokey...................Brad71, If you have the lift kit w/ a single ball bearing it may have popped out of the detent hole during re-assembly. Use stiff grease to secure the ball bearing prior to re-assembly. While you've got the bolt apart good idea to polish all mating surfaces including cocking ramp.

I also shorten the BAS by the amount the lift kit protrudes from the cocking sleeve. If you don't shorten it or put a shim between the head and the bolt body, you'll be increasing the spring tension and negating much of the gain from the kit.

It's also a good time to polish the cocking ramp and check to make sure the cocking sleeve doesn't bind inside the bolt body.

The bolt lift kit I decided on was this a thrust bearing< it cost me less than $10 so why not try. I read on another forum that you can trim the Cocking Piece Sleeve instead of the BAS which is what I did last night. Everything seems to have come together nicely and I can tell a little improvement, I guess the real test will come at the range tomorrow.

How did this work out for you Brad, looks like a good item to try.
